Pros:
1-9 are very very fun. Elevation changes, narrow fairways, and a few short open holes. Great chance of losing a disc off most of the tees, so would highly recommend spotters for just about every hole. The views of Mt Hood are spectacular, and the scenery is also a good change up from a lot of the other courses in Portland area. The course is easy to navigate on first play through with the exception of hole 4. Worth playing if your in the area, but not the kind of course worth making the trip for.
Cons:
10-18. I understand that this being on a mountain, you have to come down so your options are limited. However i think the Zig-Zag option down the mountain was a terrible choice. It's boring, overgrown, and losing discs is deceptively easy in the fairway shrubbery. Also watch out for the mountain bikers. Not as much a con as it is a noticeable hindrance.
Other Thoughts:
$7 per person. per person. per person. Make sure that's clear to everyone you're playing with before heading out. Otherwise you'll get to listen to "i cant believe i had to pay $7 blah blah blah" all the way down.
